Different unit & TDS

[Notsolostfish]

Hi I'm new to saltwater buying my first saltwater tank in a week. And I'm making sure I got my basics covered. I have an RO unit I use for my 75 gallon freshwated tank https://www.nilocg.com/shop/600-gpd...ng-water-filtration-system-with-booster-pump/

My tds from it is 2. Do I need a different unit for saltwater? Like do I need DI? Is 2 really bad?

Reason why I got rodi instead of di was reading lots say that small 2ppm could be anything and that anything could be something bad that you adding to the tank and it accumulates and accumulates etc so didnt want take risk so just got rodi unit ^_^
